Answer:
Transaction cost
Explanation:
Transaction cost is defined as costs that a person bears in the process of buying or selling of a product.
For example the commission that is paid to a broker for completing a transaction, cost of transportation that is spent when completing an exchange, and time for completing the purchase are all examples of transaction cost.
In the given instance transaction cost is exemplified by the investment a seller makes in equipment or in the hiring of skilled employees to supply the product or service to the buyer.
